General ⇒ Way to produce a round emphasized 'a' in sans serif mode?

[mutzinet]

Hi there,

I'm writing a presentation in beamer, with the default sans serif font.

In a formula, I have a "chemical activity" whose symbol should be a round italic 'a', like that produced by

Code: Select all

\textrm{\emph{a}}

with a roman family. Is there a way to produce that type of 'a' but with the same sans serif font as the rest of the beamer document?

Thanks a lot in advance if someone knows how to produce that.

\textsf{\emph{a}} perhaps?
